I would assume there is some expectation that Unity's store is selling assets that are able to be used, and not stolen/using someone else's IP.
If Unity discovers a asset is stolen they will remove it and warn or ban the publisher. I know this as I have had stolen assets removed from the store before.
"9.1
The Assets are protected by copyright laws and international copyright treaties, as well as other intellectual property laws and treaties."
Unity's license is fully legal and covered.
"2.1
You agree that Unity may stop (permanently or temporarily) providing the Unity Asset Store (or any features within the Unity Asset Store) to you or to users generally at Unity’s sole discretion, without prior notice to you."
"10.1
END-USER UNDERSTANDS AND ACCEPTS THAT PRIOR TO PLACING ANY ASSET ON THE UNITY ASSET STORE, UNITY DOES NOT UNDERTAKE ANY LEGAL OBLIGATION TO MONITOR, PRE-SCREEN, REVIEW, FLAG, FILTER, MODIFY, REFUSE OR REMOVE ANY ASSET OR THEIR CONTENT FROM THE UNITY ASSET STORE. CONSEQUENTLY, END-USER EXPRESSLY UNDERSTANDS AND AGREES THAT ITS USE OF THE ASSETS IS AT END-USER'S SOLE RISK AND THAT THE ASSETS ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTY OF ANY KIND, TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW. IN PARTICULAR, LICENSOR, ITS SUBSIDIARIES, HOLDING COMPANIES AND AFFILIATES, AND ITS LICENSORS DO NOT REPRESENT OR WARRANT TO END-USER THAT:
(A) END-USER'S USE OF THE ASSETS WILL MEET END-USER'S REQUIREMENTS,
(B) END-USER'S USE OF THE ASSETS WILL BE UNINTERRUPTED, TIMELY, SECURE OR FREE FROM ERROR,
(C) ANY INFORMATION OBTAINED BY END-USER AS A RESULT OF END-USER'S USE OF THE ASSETS WILL BE ACCURATE OR RELIABLE, AND
(D) THAT DEFECTS IN THE OPERATION OR FUNCTIONALITY OF ANY SOFTWARE PROVIDED TO END-USER AS PART OF THE ASSETS WILL BE CORRECTED."
Meaning that if it is discovered that you broke the license they can do as they wan't and because you agreed to it there is nothing you can do. Yet at the same time they have no legal obligation to monitor the assets on the store, so you can't take legal action against them if they don't.
Edit:
Unlike many other licenses that gives a court location Unity uses this:
"13.1
This EULA and END-USER's relationship with Licensor under this EULA, shall be governed by the laws of Denmark without regard to its conflict of laws provisions. Any dispute arising out of or in connection with this Agreement, including any disputes regarding the existence, validity or termination thereof, shall be settled by simplified arbitration arranged by The Danish Institute of Arbitration in accordance with the rules of simplified arbitration procedure adopted by The Danish Institute of Arbitration and in force at the time when such proceedings are commenced. Notwithstanding this, Provider agrees that Licensor shall still be allowed to apply for injunctive remedies (or an equivalent type of urgent legal relief) in any jurisdiction."
Meaning that no matter what court you go to you will be judge under Danish law.
